Title: Process for preventing discoloration in vinylacetoxysilanes
Inventor: SEILER CLAUS-DIETRICH
IPC: C07F7/18
Filed: 1991-07-05
Abstract: Abstract of the Disclosure A method of preventing discoloration of a vinyl-acetoxysilane is disclosed.  The method comprises admixing the vinylacetoxysilane with of from 25 to 500 ppm of a compound selected from the group consisting of 3,5-di-tert.-butylpyro-catechol, 2,6-di-tert.-butyl-4-methylphenol, 2-mercaptobenzimida-zole, and mixtures thereof.  The vinylacetoxysilane so stabilized does not discolor for a long period of time, usually more than one year.  Vinylacetoxysilanes, which are useful as crosslinking agents in the preparation of compositions curable to elastomers on contact with moisture normally discolor after a few days to a few weeks after being prepared, which limits their use.

IPC: B66D3/22
Filed: 1991-08-14
Abstract: A load brake for a rotating drum of a hoist having a drum drive motor positioned adjacent a first end of the drum and a motor drive shaft extending through the drum and projecting out a second end of the drum opposite the motor end of the drum, and a drive gear affixed to the end of the motor drive shaft projecting from the second end of the drum for reducing the drive speed of the motor.  A toroidal drive shaft is positioned coaxially of the motor drive shaft and is affixed to and extends from the drive gear towards the second end of the drum.  The load brake is positioned coaxially of and is affixed to the toroidal drive shaft between the gear drive and the second end of the drum for transmitting rotating drive force from the gear drive to the drum and braking a load on the drum and the motor during lowering of a load on the hoist.  The load brake includes a friction plate adjacent the second end of the drum.  The friction plate and second end of the drum each have circumferentially positioned meshing gear teeth for driving rotation of the drum by the load brake means.  The gear teeth may be axially directed splines which may have an involute gear profile.  The load brake means including the meshed gear teeth of the drum are disposed coaxial with and radially spaced from the motor drive shaft so that the gear teeth rotate independently of the motor drive shaft.  The splines are slidable in axial directions to permit the load brake to also move in axial directions to engage and disengage braking friction surfaces of the load brake.

Title: Error detection encoding system
Inventor: WENG LIH-JYH
IPC: H03M13/00
Filed: 1991-08-15
Abstract: ABSTRACT      An encoding system encodes up to 64 kilobytes of data using a binary Bose-Chaudhuri-Hocquenghem (BCH) error detection code.  The code has as a generator polynomial g(x):   g(x) = (x20 + x17 + 1) * (x+1) * (x20 + x3  + 1) *         (x20 + x3  +  x2  + X + 1)-which in octal representation is:           g(x) = 4400001 * 3 * 4000011 * 4000017 where * and + represent Galois Field multiplication and addition, respectively.  The associated primitive polynomial is X20 + X17 + 1.  The encoder encodes the data using a code based on a polynomial f(x), which is g(x) multiplied by a factor, b(x) = x3 + x + 1, or:   f(x) = (x3 + x + 1) * (x20 + X17 + 1) * (x+1) *           (X20 + x3 + 1) * (X20 + x3 + x2 + X + 1) =   which in octal representation is:      f(x) = 13 * 4400001 * 3 * 4000011 * 4000017 The inclusion of the factor in the code enhances the code's burst detecting capabilities.  The code is capable of detecting 7 random errors, and a single burst error of up to 64 bits or double burst errors of up to 24 bits each.

Title: Apparatus and method for precisely controlling the excision of obstructive tissue in a human blood vessel
Inventor: FISCHELL ROBERT E
IPC: A61B18/20
Filed: 1991-09-03
Abstract: ABSTRACT            A means and method is described that uses a tissue excision (atherectomy)  catheter  system  for  creating  a  passageway through obstructive tissue in a blood vessel of a human body such that the passageway has a greater luminal diameter than the outside diameter of a percutaneously inserted catheter used to  create that passageway.  A   guide wire  is  first percutaneously inserted into the blood vessel and  advanced through the obstructive tissue.  A percutaneously inserted catheter is then advanced over the guide wire and it cuts through the obstructive tissue while the blood vessel  is compressed  at the site of the obstructive tissue by means of an externally applied pressure cuff.   The compressional force on the blood vessel is then released and the catheter and guide wire are removed from the blood vessel.   This procedure results in a luminal diameter of the passageway cut  in  the  obstructive  tissue  that  is  larger  than  the outside diameter of the tissue excision catheter.

Title: Oil blends
Inventor: VAN BODEGOM BERTUS M
IPC: A23D9/00
Filed: 1992-01-08
Abstract: Salid oils largely comprise refined vegetable oils.      Olive oil is unique in that this expensive oil is used unrefined for it's flavour whereas the other lower cost oils are refined prior to use. There is a need for salad oils of improved nutritional quality and reduced cost.      We have now determined that an oil blend comprising at least 2% of unrefined olive oil and at least 100 of one or more unrefined liquid vegetable oils comprising at least 20% linoleic acid is sufficiently stable on storage to be used as a salad oil. It is believed that the off-flavour components produced from the non-olive component are to a large extent masked by the unrefined olive oil.

Abstract: Appareil et procédé de montage d'un simulateur de rayons X existants et de calcul d'une image tomographique calculée rétroprojetée. Le réseau de détecteur (26) est linéaire et sort des signaux provenant des photodiodes montées dans le réseau, lesquels signaux sont envoyés à un préprocesseur (32) à des fins de lissage, correction et filtrage et traitement ultérieur pour transformer le signal de celui produit par rayon X provenant d'une source de rayons en éventail (12), par exemple dans un système de coordonnées polaires, en un signal qui aurait été produit par un détecteur dans le réseau de détecteur et sur lequel un faisceau parallèle est incident sur un système de coordonnées cartésien. Les données transformées sont converties en une valeur d'échelle des gris pour un élément d'image ayant une position spécifique dans le système de coordonnées cartésien et sont affichées de manière appropriée. Les données sont prises à chaque angle incrémentiel au fur et à mesure que la source de rayons (12) et le réseau de détecteurs (26) tournent autour d'un objet cible (18). Le procédé de reconstruction de cette image rétroprojetée implique la correction et le lissage des signaux de sortie, la mise à l'échelle de ces signaux corrigés et lissés, et le convolutionnement des signaux mis à l'échelle en données caractérisant le rayon qui est incident sur chaque élément détecteur individuel en données d'intensité équivalente si le rayon incident avait eu son origine d'une source de rayon parallèle. L'invention concerne également des procédés de correction des données pour des lectures incorrectes de détecteur et pour le déplacement du réseau de détecteur (26) en conséquence à la rotation décentrée de la source de rayons X (12) ou du réseau de détecteurs (26) ou des deux.

Title: Staged combustion of fuel or sludge to reduce nitrous oxide emission
Inventor: WILLIAMS ROBERT M
IPC: F23C6/02
Filed: 1992-09-03
Abstract: A system and apparatus is disclosed for delivering fuel to a furnace using an inert gas medium which has acquired moisture from the application of the furnace stack gas for drying the incoming fuel material during the reduction of the fuel to a desired size for combustion in the furnace.  The use of an oxygen deficient inert gases medium as a propellant to deliver the fuel to the furnace is augmented by supplying air to the furnace to establish a staged combustion environment in the furnace to avoid the generation of high levels of the pollutant nitrous oxide which is understood to be generated by high flame temperatures and with high oxygen and nitrogen concentrations.
